Looking Forward For Some Help

[IckAz]

Hello guys, I am here to ask you for some help.

 I am looking forward for some passive or smth to add on my mobs to "remove" reflect .

I have a party zone spot where mobs have tons of damage and people use non armored tanks to kill it. 

I need some way to add a passive to mobs or develop them to avoid this action. Thanks in advance!

Decrease the effect of vengeance and such.

Theres nothing like no reflect passive from any boss, right?

Nop, I dont think so.
